Richard III Tower halfpenny to cross the block at Baldwin's

Baldwin's will offer a Richard III halfpenny in its Ancient Coins, British Coins and Commemorative Medals at the Coinex expo in London on September 25.

The lot, struck at the Tower of London during Richard's reign (1483-1485), isvalued at 3,000-5,000 ($4,937-8,228). It is one of a number of pieces on offer fromthe David Sellwood collection.

Richard III's bones were exhumed in a car park in Leicester in 2012

Steve Hill, director and head of English coins at the auction house, commented: "I cannot recall seeing a better example of a Richard III Halfpenny than this recent discovery. It is a superb little coin."

It's alsolikely to receive a boost invalue following the recent discovery of Richard III's bones in a Leicester car park.

Archaeologist Richard Buckley of the Univeristy of Leicester told the Leicester Mercury, a local newspaper: "What's great about showing people pictures of Richard III's coins is that it highlights why Henry[Tudor]needed to put him on public display in Leicester to show that he had been killed.

"The coins have very stylised portraits which could be images of anybody, and ultimately most people outside court would have no idea what he looked like - whereas many people in Leicester saw him a couple of days before Bosworth and would recognise him."
